PUMP.

SPECIFICATION forming part of Letters Patent No. 386,910, dated July 31,1888.

(No model.)

To all whom it may concern.-

Be it known that I, HENRY M. \VYETH, a citizen of the United States,residing at Oouncil Bluffs, in the county of Pottawattamie and State ofIowa, have invented a new and useful Improvement in Pumps, of which thefollowing is a specification.

My invention relates to an improvement in pumps; and it consists in thepeculiar construction and combination of devices, that will be morefully set forth hereinafter, and particularly pointed out in the claim.

In the drawings, Figure l is a side elevation ofa pump embodyingmyimprovements. Fig. 2 is a vertical sectional view of the same. Fig.3is ahorizontal transverse sectional view taken on the line 00 00 ofFig. 2. Fig. 4 is a vertical sectional view of my pump when adapted foruse as a single acting force-pump. Fig. 5 is a similar view of myinvention when adapted for use as a lift and atmospheric pump.

A represents the pumpcylinder, which is made of a block of wood boredlongitudinally in the direction of the grain and then split into twopieces, B. The ends of the said pieces are grooved on the inner side, asat G, and are thereby adapted to receive heads D, one of which isprovided with a central opening, E, for the rod of the plunger F. Whenthe heads are placed in position in the grooves O and the plunger isarranged in the bore of the cylinder, the parts B are secured togetherin order to confine the heads and the plunger. On the inner sides of theheads are inwardlyopening Valves G.

H represents an opening made in the pumpcylinderjust above the lowerhead, and I represents a similar opening made in the cylinder just belowthe upper head. In the outer side of the pumpcylinder, at the lower endthereof, is a vertical recess, K, which communicates with the opening H.

L represents a flat block, which is made of wood and is trimmed at itsupper end to form an extension, M, to which a pipe may be attached. Avertical bore, N, extends through the block and its extension. The lowerend of the bore communicates with the upper portion of the recess K at apoint directly opposite the opening H.

0 represents the transverse opening, which is made in the inner side ofthe block L and communicates with and intersects the bore N at a pointopposite the opening I, the said opening 0 being larger than the openingI and forming a seat for a ball-valve, P. The block L is placed againstthe block A and rests between a pair of vertical flanges, It, with whichthe block A is provided, and U shaped clamping-bolts S have their armsextended through horizontal aligned openings in the pieces B, and areengaged by clampingnuts T at their outer ends, the central portions ofthe said bolts embracing the block L, and thereby the said bolts securethe said block L to the cylinder and secure the parts of the lattertogether.

The operation of this form of my invention is as follows: The pump-eylinder is submerged in the water at the bottom of the well or cistern. Inthe recess K is secured a verticallymovable slide, U, which is adaptedto cut off communication between the opening II and the lower end of thebore N when the slide is raised and to establish communication betweenthe said opening and the bore N when the slide is closed. At eachupstroke of the plunger water is drawn in through the lower valveheadinto the cylinder, and the water in the upper part of the cylinder isforced through the opening I, past the valve P, and through the upperportion of the bore N. \Vhen the plunger descends, water in the lowerportion of the cylinder is forced through the opening E into the bore Nand up past the valve 1, thereby causing the latter to close the openingI. \Vhile the plunger is descending, water is drawn into the upperportion of the cylinder through the upper valve-head.

It will be readily understood from the foregoing that when the pump isthus constructed it forces water at each stroke of the plunger in eitherdirection, and thereby the pump is rendered double-acting.

In order to adapt my pump for use as a single-aeting force and liftpump; I remove the upper valved head, I). and substitute a solid head,D, therefor, remove the solid plunger E and substitute therefor aplunger, E, having an upwardlyopening valve, Ff. The slide U is thenraised in the recess K, so as to close the opening II. \Vhen thusarranged, the

plunger draws water into the lower end of the cylinder on the upstrokeand forces the water in the upper end of the cylinder up through thebore N past the valve P. On the succeeding downstroke of the plunger lhevalve E opens and the valve in the bottom head, D, closes, thus causingthe water to pass through the plunger as it descends.

In order to convert the pump into a singleacting atmospheric and forcepump, I insert the upper end of the suctionpipe V into the lower end ofthe bore of the pump-cylinder and provide the upper end of the saidsuctionpipe with an upwardly opening valve, V. When thus arranged, thesuction-pipe extends down into the water and the pump-cylinder is raisedaconsiderable distance above the level of the water, as shown in Fig. 5.

By providing the pump with the ball-valve P, seated in the enlargedopening 0, the water in the upper portion of the bore N will be causedto flow through the opening I into the cylinder when the pump is not inoperation, thereby preventing the water from remaining in the upperportion of the bore N and stagnating therein and becoming frozen in coldweather.

Having thus described my invention, I

the lower end of the cylinder and the bore N,

substantially as described.

In testimony that I claim the foregoing as my own Ihave hereto affixedmy signaturein presence of two witnesses.
